不定式省略to的10种情况

九、并列不定式与to的省略

当两个或多个作用相同的不定式并列时，通常只需在第一个不定式前用 to，其余不定式前的 to 可以省略。如：

I’d like to lie down and (to) go to sleep. 我想躺下睡觉了。

Will you go to see the film or (to) dance? 你要去看电影还是要去跳舞？

I’ll go to see him myself and (to) ask him about it. 我将亲自去看望他并问一问那件事情。

但是，如果两者有对比关系，则后面不定式前的to不可省略。如：

To try and fail is better than not to try at all. 尝试而失败总比不尝试好。

十、固定搭配与to的省略

1. let类固定搭配：let fall (无意中说出)，let fly(发射、攻击)，let go (放开)，let slip (放走)，live and let live (自己活也让别人活)等。如：

She let slip a chance to work abroad. 她错过了出国工作的机会。

The dog’s got a stick between his teeth and he won’t let go. 那狗叼着一根棍儿不松口。

He aimed carefully and then let fly. 他仔细瞄准之后便开了枪(www.hxen.net)。

I guessed what was happening from a few words she let fall. 我从她说的几句话中猜出发生什么事了。

2. make类搭配：make believe (假装)，make do (凑合着用)等。如：

The boys made believe (that) they were astronauts. 男孩子们假扮成航天员。

We were in a hurry so we had to make do with a quick snack. 我们时间很紧，只好胡乱吃了顿小吃。
